Why do solar panels have two negative poles

Magnets for short don''t have a positive pole and a negative pole, but south and north. This is meant to distinguish between a dipole (mentioned above) and the magnetic orientation. Iron, being prominent for the ferromagnetism, is per se not a permanent magnet, the atoms inside are oriented somewhat random to each other.

Solar panels are slightly different from other possibilities because of the bypass diodes, but if you are between the source and the panels you''ll still get the whole ac voltage, and after the panels (or in the middle somewhere) you''ll get half wave rectified ac which, if the source is 120, is still ~80vdc which no longer falls under the ...

Touching panel negative and positive wires

If you look at a solar panel datasheet and compare the current at maximum power point (Imp) to the short circuit current (Isc) you will notice the short circuit current is not significantly higher than the normal operating current. Therefore there is very little potential for panel damage by simply touching the wires together.

How to Wire Two or More Solar Panels in Parallel

If we have two solar panels with same voltage and power, the connection will be very simple.. As clearly visible in the picture, it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.

Many double pole (240VAC) breakers have a single toggle, but they are still breaking two circuits. As an aside, you can use two single pole ( 2 x 120VAC) breakers for a 240VAC load if the two toggles are connected together so if either trips both shut off.

When Do You Need to Fuse Solar Panels? (and how to do it)

Remember that with parallel wiring the amperage increases, so the total short circuit current of this solar array is 36.27 Amps (12.09A x 3 panels = 36.27A).. In the event of a fault or short circuit in one of the panels, the other two panels would dump 24.18 Amps of current into the faulty panel (12.09A x 2 panels = 24.18A).
